Abstract

1. Pneumatically driven percussion drill, in particular deep drill hammer (10), including an outer tube (12) and a passage (18) in an upper cap (14) for connection to a compressed-air source and, if applicable, to boring rods, including a control unit (24) supported in the cap and a central tube (30) joined to the control unit, the central tube being designed as air feeding and air discharging tube having passages (31...38) as well as a gating insert (40), a hollow ram (50) being slidably guided along the insert in the outer tube, and including a lower mounting cap (94) which has an inner profile and which supports, for up-and-down movement, a hollow shaft (86) having a matching outer profile as well as flushing bores, wherein at least one cone (60, 61) is provided or attachable at the crown head (58) and/or at the central tube end and/or inside the ram end.
